Psycroptic is a technical death metal band from Hobart, Australia. The band is currently signed to Nuclear Blast and has so far released four full length albums. They formed in 1999 by brothers Dave (drums) and Joe (guitar) Haley who had previously been involved in a band called Disseminate. That group had recorded a demo in 1998 before disbanding. Shortly afterward, the Haleys created Psycroptic with Cameron Grant on bass and vocalist Matthew Chalk, who soon after became a drummer with established local death metal act M.
